摘要:

本文通过研究环氧树脂各配方体系的成膜性、室温胶膜状态、动态DSC曲线特征以及体系的粘温特性,初步确定中温热熔膜浸法用树脂体系配方为固化剂/促进剂/环氧树脂的质量比为5-6/2-3/100。该质量比下,体系可中温固化,成膜性工艺性佳,室温胶膜韧性好,满足了热熔膜浸法制备预浸料的要求。

Abstract:


【Abstract】 According to the film forming property,the resin film's state(in room temperature),DSC curves and the viscosity-temperature characteristics of epoxy matrix,the resin film system which was used as moderate-temperature hot-melt prereg has been designed.The formula involves curing agent/accelerator/epoxy resin with mass porportion of 56/23/100.This system can be cured at mid-temperature.With very exlellent film forming properties,the film was prepared with good toughness at room temperature,which could meet the requirements of moderate-temperature hot-melt prepreg.
